Names: DNA ADP-ribosyl transferase (DarT) domain
Function: The bacterial DNA ADP-ribosyl transferase (DarT) protein is a toxin
 that has been shown to transfer ADP-ribose from NAD(+) onto thymidine bases
 present in single-stranded DNA (ssDNA) specifically at the four-base motif
 TNTC, and to have no activity on RNA or protein targets.

CC   -!- CATALYTIC ACTIVITY: Reaction=a thymidine in DNA + NAD(+) = an N-
CC       (ADP-alpha-D-ribosyl)-thymidine in DNA + H(+) + nicotinamide;
